Hi there,
Have you tried:
.post-title, .post-title a, .post-title a:hover, .post-title a:visited {display: none;}
Just a heads up that use can use the (free) add-on Firebug for Firefox to isolate elements such as this. Josh Lobe has some useful You-tube tutorials on how to use Firebug. Ken also has an article on his blog, which can be found here.
Hope that’s what you are after.
Regards,
Sharon 🙂
